MSAST042SCG4R6BWNA01 Equivalent & Substitute Parts

Part Overview

The MSAST042SCG4R6BWNA01 is a 4.6 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 25V operation with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is packaged in 01005 (0402 Metric) form factor and is supplied in Tape & Reel (TR) packaging. The part is currently in Active product status with 698 pieces available in stock.

Substitute parts become necessary when Tape & Reel packaging is unavailable, when inventory constraints exist, or when alternative packaging formats are required for specific manufacturing processes. The substitute identified maintains identical electrical specifications and mechanical compatibility while offering different packaging and availability characteristics.

Substitute Part Grouping Explanation

Substitution of the MSAST042SCG4R6BWNA01 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 4.6 pF
• Capacitance tolerance: ±0.1pF
• Voltage rating: 25V
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 125°C

Mechanical Equivalence Requirements:

• Package type: 01005 (0402 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum thickness: 0.009" (0.22mm)

Compliance Equivalence Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• ECCN: EAR99
• HTSUS: 8532.24.0020

The identified substitute part TMK042CG4R6BD-W meets all electrical, mechanical, and compliance requirements. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. Both formats are compatible with automated assembly equipment, with selection dependent on manufacturing process requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: MSAST042SCG4R6BWNA01

The MSAST042SCG4R6BWNA01 is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and long-term availability. It is supplied in Tape & Reel (TR) packaging, which is the standard format for high-volume automated assembly operations. Current inventory of 698 pieces supports immediate procurement requirements.

Substitute Selection: TMK042CG4R6BD-W

The TMK042CG4R6BD-W is a valid electrical and mechanical equivalent suitable for applications where Cut Tape (CT) packaging is acceptable or preferred. This part carries "Not For New Designs" status, indicating the manufacturer is transitioning away from this product line. However, it maintains full electrical equivalence and compliance certifications. The significantly higher inventory level (41029 pieces) provides availability for legacy system support or high-volume requirements where Cut Tape format is compatible with assembly equipment.

Both parts are ROHS3 compliant, carry MSL 1 rating, and operate across the identical temperature range. Selection between them should be based on packaging format compatibility with manufacturing processes and product lifecycle requirements.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG4R6BD-W be used as a direct replacement for MSAST042SCG4R6BWNA01 in new designs?

A: TMK042CG4R6BD-W is electrically and mechanically equivalent but carries "Not For New Designs" status. For new designs, MSAST042SCG4R6BWNA01 is the appropriate selection due to its Active product status and manufacturer support commitment.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place equipment with reel feeders. Cut Tape packaging supplies components on tape segments, typically used with manual or alternative feeding systems. Both formats contain identical components; selection depends on assembly equipment compatibility.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts are packaged in 01005 (0402 Metric) form factor with identical dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both MSAST042SCG4R6BWNA01 and TMK042CG4R6BD-W are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the "Not For New Designs" status on TMK042CG4R6BD-W?

A: "Not For New Designs" indicates the manufacturer is discontinuing this product line. While the part remains available and fully functional, it should not be selected for new product development. It is suitable for legacy system support, maintenance, or applications where existing inventory must be utilized.

Q: Are the electrical specifications identical between both parts?

A: Yes. Both parts provide 4.6 pF capacitance with ±0.1pF tolerance, 25V voltage rating, C0G/NP0 temperature coefficient, and -55°C ~ 125°C operating temperature range. Electrical performance is identical.
